Bianca Andreescu’s mother has the funniest reaction after her daughter wins the US Open

Canadian teenager Bianca Andreescu capped a meteoric rise this year by beating Serena Williams in the US Open final to claim her first Grand Slam title.

The 19-year-old is the first woman to win the US Open in her tournament debut in the Open era, which began in 1968.

But her mother's reaction to her victory on Saturday would make you think otherwise.

A gif that is circulating on the internet shows the impeccably dressed Maria Andreescu politely clapping at the end of the tournament.

Bianca retweeted the gif a couple of days later, adding that she'll "never be that cool."

And she later replied with a glamorous shot of her mother getting ready for the show.

As well as a clip of Maria hugging her daughter after her victory.

People agreed that Maria was very cool and even said she was channelling 'Helena Bonham Carter vibes'.

But this is not the first time Maria Andreescu has served courtside lewks at her daughter's matches...
